Abstract: A drilling system for use at a wellhead has a plurality of modules each containing rig component equipment. The plurality of modules are connected or interconnected together so as to form a drilling rig. Each of the plurality of modules has a size adapted to be lifted by forklift or a front end loader. The plurality of modules are arranged such that one end of the plurality of modules is adjacent to the wellhead. A pipe handling system is positioned adjacent to one end of the plurality of modules. A ventilation system is cooperative with the plurality of modules so as to move air toward or away from heat-generating equipment in the plurality of modules.

Abstract: An automated system that constantly collects data from the tank monitor system, the fuel dispensing system and the point of sale equipment for the purpose of inventory reconciliation through statistical data analysis. The results of this data analysis is then transmitted by telephone means periodically to a central computer for further processing. This system will notify the central computer to indicate that a problem exists when any of the inventories have reached a minimum level or fail to reconcile due to unknown reasons. This system is designed to prevent loss of sales due to insufficient inventory and/or loss of inventory due to miscalibration of fuel dispensers, theft or tank leakage. This invention will interface with any equipment capable of serial communication and can be installed at existing service stations with a minimum amount of disruption to commerce.
